You need to call CoCreateInstance with CLSID_WICImagingFactory argument. See this question, for example: CoCreateInstance of IWICImagingFactory

Or this intro: Introduction to WIC: How to use WIC to load an image, and draw it with GDI?

Or, this sample:

    hr = CoCreateInstance(
        CLSID_WICImagingFactory,
        NULL,
        CLSCTX_INPROC_SERVER,
        IID_IWICImagingFactory,
        reinterpret_cast<void **>(&pWICFactory)
        );

Or this SimpleDirect2DApplication sample which features Driect2D and WIC capabilities to load from file.
